Special Issue Information

Dear Colleagues,

Increasing the localization of drugs to hematologic or solid tumor cancer cells by targeted drug delivery holds great promise to improve the treatment of cancer with conventional and nonconventional drugs. Given the broad range of drug types, cancers, and tumor heterogeneities, the successful clinical application of targeted drug delivery will continue to require the preclinical development of multiple drug delivery approaches for selection and further clinical development.

This Special Issue seeks to highlight original research articles and reviews on the preclinical development of targeted drug delivery approaches to improve the pharmacotherapy of cancer with conventional and nonconventional drugs. Research areas include any approaches that improve the treatment of preclinical cancer models with small-molecule (<900 Da) or macromolecule drugs (e.g., biomolecules) (e.g., increase potency and/or efficacy, decrease toxicity) by increasing the localization to the site of action in hematologic cancer cells or solid tumor/tumor-associated cells in primary and/or secondary tumors.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceutics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Background: As a modulator of pre-mRNA splicing, the anti-cancer agent indisulam can induce aberrantly spliced neoantigens, enabling immunologic anti-tumor activity. Consequently, combining indisulam with immunotherapy is expected to be a promising novel approach in cancer therapy. However, a prerequisite for such a combination is that immune effector cells remain functional and unharmed by the chemical. Methods: To ensure the immunocompetence of human immune effector cells is maintained, we investigated the influence of indisulam on ex vivo-isolated T cells and monocyte-derived dendritic cells (moDCs) from healthy donors. We used indisulam concentrations from 0.625 µM to 160 µM and examined the impact on the following: (i) the activation of CD4+ and CD8+ T cells by CD3-crosslinking and via a high-affinity TCR, (ii) the cytotoxicity of CD8+ T cells, (iii) the maturation process of moDCs, and (iv) antigen-specific CD8+ T cell priming. Results: We observed dose-dependent inhibitory effects of indisulam, and substantial inhibition occurred at concentrations around 10 µM, but the various functions of the immune system exhibited different sensitivities. The weaker activation of T cells via CD3-crosslinking was more sensitive than the stronger activation via the high-affinity TCR. T cells remained capable of killing tumor cells after treatment with indisulam up to 40 µM, but T cell cytotoxicity was impaired at 160 µM indisulam. While moDC maturation was also rather resistant, T cell priming was almost completely abolished at a concentration of 10 µM. Conclusions: These effects should be considered in possible future combinations of immunotherapy with the mRNA splicing inhibitor indisulam. Full article
